"IggyTail" is a term made popular by the fans of Australian hip-hop recording artist and model Iggy Azalea, referring to her very long blonde ponytail, a hairstyle in which some, most or all of the hair on the head is pulled away from the face, gathered and secured at the back of the head with a hair tie, clip or similar device, and allowed to hang freely from that point. It gets its name from its resemblance to the undocked tail of a horse or pony.

Iggy Azalea is usually seen with this look, from several photo shoots to music videos and live performances where she also whips it in different ways, known as her signature moves.

This term is commonly used on social networks such as Twitter and Tumblr.
